'inaaaea COLUMBUS a. THOMAS, or ravnr'rnvrmn, NORTH 'GAS-REGULATING VALVE.

To all whom may concern Be it known that l, COLUMBUS THOMAS, a citizen of the United States, residing at have invented construction and inthe combination and arf rangement of the several parts of my improved device whereby certain important set forth.

advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully The novel features of the inventionl willv be carefully defined in the appended claim.

invention may be the better understood, will now proceed lto describe the same with reference tothe accompanying drawings, wherein-'- A lFigure 1 is an elevational view of a pilot constructed in accordance with an embodi. ment of my invention, a main burner being shown in fragment and asupply' pipe being indicated in section; and Fig. 2 is alongitudinal sectional view taken through the cylinder includedin myl improved pilot, as herein disclosed, the c'oacting portions of the pipes or tubes being shown in elevation and in fragment. Y

As disclosed in the accompanying drawings, 1 denotes a' cylinder of predetermined dimensions and having its opposite ends Open, such open ends beingI adapted to be closed b v the heads 2 and 3 removably entherewith, such engagement being herein disclosed through the medium of conventional threads. rlhev cylinder 1 is adapted to contain a compressible body 4 preferably of mineral wool, although l have found in practice that such body will operate with advantage when formed of cotton or felt.

As herein disclosed, the body 4 is interposed between the reticulated members `5,

sra ori preferably formed of wire mesh, and one of such members is adapted to be .engaged by the inner. extremity of the controllingscrew 6,- herein disclosed as threaded through the density ofsuch body 4 may be regulated in order to control through s uch cylinder.

' ln order that the body 4 may` operate witlry greater facility,

l nd it of advantage body 4 the expansible member 17, herein possessing4 the requisite tension. In' communication with the cylinder 1 in close proximity tothe head 2 is a tube or pipe 7 adapted to lead from the supply pipe 8 of the main gas burner, as is generally done in devices of this character. The head 3 ing its exteriorl surface threaded and adapt-v ed to be engaged by the sleeve 10 Slidably vmounted upon the tube or pipe 11, which pipe or tube 11 is adapted to be directed so as to properly terminate in close proximity to the main burner 12, such extremity being the flow'of the gaseousr iuidI is provided 'with a nipple 9 ,hav-v head 2 whereby it willloe observed that the i especially' when .the'flow through the pilot is adapted to be increased,

to embed within such provided lwith the tip 14 of any ordinary or preferred type. or pipe 11 coacting with the nipple 9 is provided withl an enlargement or annular flangel adapted to'register-with the free '.llhe extremity of the tube end ofthe nipple and for the purpose of efj fecting a proper joint, lf-fnd it ofl advantage to interpose between such head or angel and the nipple 9 a washer 16 formed of `as- .through lthe pilot, and it is this 'arrangeservesto. avoid the manifest dls- Y ment Awhich advantage in the pilots generally employed,

as such engagement or coaction with the controlling screw has been found 'to result in to materially interfere with the operation ofthe pilot and in some instances to such f like. 'It is thought to be ob- 4 is interposed between extent as to so clog or as to entirely close the same.

From the foregoing description, it is thought to be obvious that a gas regulating valve constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by-re'ason of the convenience and facility with which it mayfbe assembled and by reason. of the ef-l lfectiveness with which itv performs its functions, and it will also obvious that my invention is susceptible 'df'some change and modificationA without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limitingyself`to the precise arrangement and formation of the shown in carrying out my invention in practice.

I claim:

ends, a screw threaded through one end of` the opposite end being provided with a discharge opening, said member being providedv in a, side thereof with an induction opening, a permeable and compressible body positioned within the tubular member and mterposed` between the end proinduction opening, the-space between the inner end of the compressible body and the end of the tubular member affording an exansion chamber, an expansi-ble member emedded within the compressible body, and a perforated member disposed in contact ywith the "inner end of the compressible body and inner end of the screw is adapted to contact.

In testimony whereof I Vhereunto aiiix my 4'signature in the presence of two witnesses.
